Unzip the file win32diskimager.zip, then double-click Win32DiskImager.exe in the unzipped folder called win32diskimager. Yes to confirm you want to run the program. Then it will start. Once you've established that it works, close it down and plug in your SD card.

Using Win32DiskImager

Having plugged in your SD card, (re)start Win32Diskimager (right click on mouse and choose Run it as Administrator). Choose the drive you want to copy the image to (in my case J: ).

choose the drive with your SD card to write the OS image on

Then click on the folder icon and choose the unzipped .img file from earlier that you want to put on the SD card. Then click Write, to write the Operating system on the card from the .img file.

Write OS image from .img file to SD card

You will then be asked to confirm. Check carefully that you are writing to the correct device and if so, click Yes.

Check device and confirm

The progress bar will show you how far it’s got.

When it’s finished it looks like this.

Finished

Then you can eject the card reader and remove the SD card. Then you can try it out in your Raspberry Pi. If all went well, your Pi should boot up (start). It may take about one minutes. If nothing’s happened after that, look at the LEDs on the Raspberry Pi. If you only get the red power LED, either the card is not inserted properly or it can’t boot this combination of card and image, or something went wrong with the process. But in the main it should work well.
